I think problem with your variable name, you are using same variable for save new data that is $data rename with "$new_data"

public function Op_insert($data){

    $count = count($data['name']);

    for($i = 0; $i<$count; $i++){ 

        $new_data[] =  array(
            'Stock' =>$data['Stock'][$i],
            'Rate'=>$data['Rate'][$i],
            'Amount' =>$data['Value'][$i]
          );
    }
    $this->db->insert_batch('opstock', $new_data); 
}
